“Track 5 a previously unreleased single meant for “The Days of Mars” album, but ultimately deemed out of place on the record, begins with the slow reveal of a repeating electronic ring atop a rising, falling, sine-curving synth. With each additional layer—a piercing, urgent synthesizer; a deep, continuous, ever-expanding rumble; the sound of a guitar, awash in reverb—the atmosphere thickens. It’s both restless and placid, anxious and tranquil. Just over ten minutes in length, the track closes with a chorus of high-pitched synths that fade to a sparse, darkened end. This 12-inch, very likely Gonzalez and Russom’s last, also features a remix from Âme, comprised of Germany’s Kristian Beyer and Frank Wiedemann. The house duo wholly transforms the A-side into a track so unrecognizable it seems brand new, taking it far from the introspective dreamworld to a dance party in the sweaty, blissed-out, wee hours of the morning.
